The Tektronix M027  (P/N 155-0019-00) is a decimal point and spacing control monolithic integrated circuit in a 16-pin DIP, designed by Les Larson.

It consists of a decade counter, digital-to-analog converter, and input logic, and is used in the 7000 series readout system to produce a positioning signal (10-level staircase), and also to position the decimal point.
